The FCC site has provided details on a third phone that has a 1700 MHz radio compatible with T-Mobile’s future 3G network, as well as dual-band 850/1900 GSM/EDGE. The Samsung SGH-T819 is a slider with a 1.3 Megapixel camera and stereo Bluetooth. It will work with T-Mobile’s MyFaves program, but the documents did not reveal much more. Though this phone has been approved by the FCC, T-Mobile and Samsung have not announced it, nor has T-Mobile said when its 3G network will launch.
